ACN over MCP

Endpoint: https://priostack.com/mcp. This reference reproduces the live tools/list of 5 October 2026. It is an input reference, not a response specification. "Not declared" means the schema does not mark a field required; the runtime may still require it. noetic.register, initialize and tools/list need no credential; noetic.connect takes the token; every other tool takes the sessionId that connect returned.

An account may hold at most 2% of the node's capacity and 64 MiB; accounts registered from one network in the last 7 days may hold at most 10% and 512 MiB together; the node keeps 5% in reserve. Past any of these the outcome is capacity-exhausted. These shares are per account and per network, so they do not stop someone with many networks from filling the node.
